Abstract


This paper tries to find out effect of air quality of five places in eight different locations in the state of Assam. The study is to analyse the air pollution concentration in the State. Basically, sulphur dioxide (SO2), nitrogen dioxide (NO2), respirable suspended particulate matter (RSPM), suspended particulate matter (SPM) for three consecutive years 2007, 2008, 2009 were critically analysed. The annual average and Exceedence factor were also calculated in all different locations. In this study, it is observed that RSPM and SPM are high in four locations in 2007, five in 2008, and five in 2009. In critical category, we see two locations in 2007, three locations in 2008 and four locations in 2009. But, it is seen that the concentrations of SO2 and NO2 are below the prescribed limit of NAAQS of CPCB in all three consecutive years in all locations.
